More Information
Summary:The disclosure concerns an electric rotating machine (4), comprising a stator (20), a rotor (22) arranged to rotate about a rotational axis (24) in relation to the stator (20), and a cooling system (26) for cooling at least a portion of the stator (20). The stator (20) comprises a stator core (28) and a stator coil (30), the stator coil (30) having a coil end winding (32) extending axially beyond the stator core (28). At least part of the coil end winding (32) is arranged in a channel (34) extending at least partially around the rotational axis (24). The cooling system (26) comprises the channel (34) and at least one inlet (36) to the channel (34) arranged at a radially inner portion (37) of the channel (34) seen along a radial extension (38).
